Notes:
Collisional deactivation of the vibrational level v=1 of the bending mode by rare gases has been studied for both the excited A˜ 2A1 and ground X˜ 2B1 electronic states of PH2. Quenching constants have been determined. While a non-SSH behavior has been observed in the dependence of the relaxation probability upon the mass of the collision partner in the ground state denoting a possible predominance of an intramolecular V–R energy transfer process, the cross sections fit quite well the Parmenter and co-workers' potential well depth correlation rule for both the electronic states indicating that their interactions with the quenchers occur for both of them under the influence of long range attractive forces. © 1997 American Institute of Physics.
